Transition metals. Semi metals exhibit properties intermediate between those of metals and nonmetals. The number of protons in the nucleus of an atom of an element. ALKALINE EARTH METALS • show metallic properties Be being the least metallic • good conductors of heat & electricity • Mg most used as metal • Be - rare & costly • Ca, Sr, Ba - too reactive • Ra - radioactive specie. Metals like iron (Fe), copper (Cu), aluminum (Al) and gold (Ag) are often used in electronic cables and electrical circuits because of their electrical conductivity. most are hard and shiny, less reactive, examples are iron, copper, nickel and gold.
